BEARING FOR CENTRIFUGAL MACHINES.

SPECIFICATION forming part of Letters Patent N 0. 651,375, dated June 12, 1900.

Application filed February 1,-1899. gerial No. 704,208.

The upper convex segment of a sphere suspending and revolving with said spindle, and a lower concave segment of a sphere, said segments having reciprocal annular bearingfaces and having a common axis at a point above such faces, whereby the concavity in the lower segment tends to retain oil between the bearing-faces, and an oil-basin su rrounding said bearing and adapted to contain oil to immerse the spherical bearing-faces, substantially as set forth.

2. In centrifugal and other machines having a revolving spindle, the combination with said spindle, of the spherical bearing 0 having a central cylindrical hollow e, and fixed to, suspending, and revolving with, said spindle, the support f, and the oil-basin g, having a central vertical pipe 7L rising between said spindle and the support to above the bearing-faces of said bearing and support for preventing escape of oil around the shaft, sub stantially as and for the purpose set forth.

3. In centrifugal and other machines, a revolving spindle, and a bearing therefor consisting of annular bearing-surfaces, the one fixed to the spindle, in combination with an oil-basin for said bearing having an annular oil-chamber enveloping said bearing-faces and having walls rising above the latter at the inner and outer sides thereof and surrounding said spindle, said vessel having a passageway communicating between the inner and outer sides of said bearing-faces for permitting inflow of oil past said faces,whereby the oil thrown to the outer part of said chamber by centrifugal action can flow through said passage-way to the inner side of said bearing-faces for restoring the oil-level in said basin, and a continuous flow of oil across said faces can take place.

4. In centrifugal and other machines l1avinga revolving spindle, the combination with said spindle of a bearing, consisting of two reciprocal segments of a sphere having annular bearing-faces, the one segment supporting said spindle, and the other segment supporting that supporting said spindle and an oil-basin surrounding said bearing, and adapted to contain oil to immerse said bearing-faces and having walls independent of said spindle rising at their inner and outer sides, substantially as set forth.

5. In centrifugal and other machines having a revolving spindle, the combination with said spindle, of a bearing consisting of two reciprocal segments of a sphere, the one supporting and free to revolve with said spindle, and the othersupporting that supporting said spindle and free to revolve with the first, and an oil-basin surrounding said bearing and adapted to contain oil to immerse the bearing faces of said segments and revolubly supporting the latter of them, substantially as set forth.

6. In centrifugal and other machines having a revolving spindle, the combination with said spindle, of a bearing consisting of two reciprocal segments of a sphere, one supporting and revolving with said spindle, and the othersupporting that supporting said spindle, an annular washer supporting the latter segment, and an oil-basin supporting said washer and containing oil to immerse said washer.

7. In centrifugal and other machines, a revolving spindle, and a bearing therefor consisting of annular bearing-surfaces, the one fixed to the spindle, in combination with an oil-basin for said bearinghaving an oil-chamber enveloping said bearing-faces and having walls rising above the latter at their inner and outer sides, and independent of said spindle, for immersing them in oil, and means communicating between the inner and outer sides of said bearing-faces for permitting inflow of oil pastsaid faces, whereby the oil thrown to the outerpart of said chamber by centrifugal action can flow through said com municating means to the inner side of said bearingfaces for restoring the oil-level in said basin, and a continuous flow of oil across said faces can take place.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
